The specimen, holotypeIVPP V 11821, was excavated in the Xiaguan Formation dating to the Turonian-Campanian stages. It consists of a partial skeleton lacking the skull. Eight posterior dorsal vertebrae, a sacrum of six vertebrae and a tail of thirty-six vertebrae have been preserved, together with a partial ischium, a forelimb and a hindlimb. The describers considered Nanyangosaurus to be of Albian age because of its primitiveness, but the type horizon is now believed to be Turonian-Campanian in age based on plant and invertebrate fossils.[2]
Nanyangosaurus was a rather small euornithpod with an estimated length of four to five metres. The length of the femur is 517 millimetres. The forelimbs were relatively long with a long hand. The first digit of the hand was completely absent including the first metacarpal; according to the describers this was not an accident of preservation but the actual condition of the living animal. The species would then not have possessed the thumb spike typical of its relatives.

Shantungosaurus is a genus of very large saurolophine hadrosaurid dinosaur found in the Late Cretaceous Wangshi Group of the Shandong Peninsula in China, containing a single species, Shantungosaurus giganteus. The stratigraphic interval of Shantungosaurus ranges from the top of the Xingezhuang Formation to the middle of the Hongtuya Formation, middle to late Campanian in age. Shantungosaurus is so far the largest hadrosauroid taxon in the world: the greatest length of its femur is about 1.7 metres (5.6 ft), and the greatest length of its humerus is about 0.97 metres (3.2 ft).
Crichtonsaurus is a dubious genus of herbivorous ankylosaurid dinosaur that lived during the Late Cretaceous in what is now China. It was named after Michael Crichton, the author of the famed dinosaur novel Jurassic Park.
Tugulusaurus is a genus of coelurosaurian theropod dinosaur that possibly belongs to the Alvarezsauria. It is known from the Early Cretaceous Tugulu Group in the Urhe area of the People's Republic of China.
Luanchuanraptor is a genus of dromaeosaurid theropod dinosaurs from the Late Cretaceous of China. The genus is based on a partial skeleton from the Qiupa Formation in Luanchuan, Henan. They were medium-sized dromaeosaurids, the first Asian dromaeosaurid taxa described from outside the Gobi Desert or northeastern China.
The Iren Dabasu Formation is a Late Cretaceous (Cenomanian) geologic formation in the Iren Nor region of Inner Mongolia. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. The formation was first described and defined by Henry Fairfield Osborn in 1922 and it is located in the Iren Nor region of China.
The Xiaguan Formation is a Turonian to Campanian geologic formation in Henan Province of China. Dinosaur remains are among the fossils that have been recovered from the formation.
The Gaogou Formation is a Late Cretaceous (Cenomanian-Turonian) geologic formation in China. Fossil dinosaur eggs, the caenagnathid Beibeilong, and the titanosaur Baotianmansaurus have been reported from the formation.
Qiupalong is a genus of extinct ornithomimid theropods from the Late Cretaceous of what is now China and Canada.
Youngoolithus is an oogenus of dinosaur egg. It is the sole member of the oofamily Youngoolithidae, and consists of a single oospecies: Youngoolithus xiaguanensis. It consists of a single fossil nest of 16 eggs with an associated dinosaur footprint that was first discovered in 1975 in the Majiacun Formation near Houzhuang Village, Henan Province, in the Cretaceous Xiaguan Basin. The eggs are smooth, olive-shaped, and arranged in five rows. It was originally described as being a Faveoloolithid egg, however the nest is arranged quite differently than other members of that family, so it has been moved to its own oofamily, Youngoolithidae.
Ovaloolithus is an oogenus of dinosaur egg. Eggs of the genus have been found in China, Mongolia and Utah.
Linhenykus is an extinct genus of alvarezsaurid theropod dinosaur from the Late Cretaceous of Inner Mongolia, China. It is the most basal known member of the Parvicursorinae. The genus gets its name from Linhe, a city near the site where the fossil was first found and Greek nykus, "claw". The specific name is derived from Greek monos, "single", and daktylos, "finger", a reference to the fact that it is the only known non-avian dinosaur to have had but a single digit.
Linhevenator is a genus of short-armed troodontid theropod dinosaur from the Late Cretaceous (Campanian) Bayan Mandahu Formation of Bayan Mandahu, Inner Mongolia, China.
Yulong is an extinct genus of derived oviraptorid theropod dinosaur known from the Late Cretaceous Qiupa Formation of Henan Province, central China. It contains a single species, Yulong mini. It is known from many juvenile specimens that represent some of the smallest known oviraptorids.
Jiangxisaurus is an extinct genus of oviraptorid theropod dinosaur from the Late Cretaceous Nanxiong Formation of southern China. It was similar to Heyuannia, but with more strongly curved anterior claws and a thinner, frailer mandible. This find is paleontologically significant because it contributes to current knowledge about the paleogeographical distribution of oviraptorids in southern China. It was most likely a herbivorous animal along with its close relatives Nankangia and Ganzhousaurus.
Yunganglong is an extinct genus of basal hadrosauroid dinosaur known from the early Late Cretaceous lower Zhumapu Formation of Zuoyun County, Shanxi Province of northeastern China. It contains a single species, Yunganglong datongensis.
Gongpoquansaurus is an extinct genus of basal hadrosauroid dinosaur that was not formally named until 2014, while the name was a nomen nudum for many years previously. It is known from IVPP V.11333, a partial skull and postcranial skeleton. It was collected in 1992 at locality IVPP 9208–21, from the Albian Zhonggou Formation, in Mazongshan, Gansu Province, China. The specimen was first described and named by Lü Junchang in 1997 as the third species of Probactrosaurus, Probactrosaurus mazongshanensis. Following its description, several studies found it to be less derived than the type species of Probactrosaurus in relation to Hadrosauridae. Therefore, "Gongpoquansaurus" had been suggested, yet informally, as a replacement generic name. In 2014, the species was formally redescribed, and the describers erected Gongpoquansaurus.
Zhanghenglong is an extinct genus of herbivorous hadrosauroid iguanodont dinosaur known from the Late Cretaceous Majiacun Formation in Xixia County of Henan Province, China. It contains a single species, Zhanghenglong yangchengensis, represented by a disarticulated and partial cranium and postcranial skeleton.
Huanansaurus is an extinct genus of oviraptorid dinosaur that lived approximately 72 million years ago, between the Campanian and Maastrichtian, during the latter part of the Cretaceous period in what is now China, in the Nanxiong Formation.
Zuoyunlong is an extinct genus of herbivorous ornithischian dinosaur belonging to the Hadrosauroidea, that lived during the Late Cretaceous in the area of present China.
